Abstract

Guide d'ondes circulaire hélicoïdal permettant de réduire l'affaiblissement dans les courbes. Il comporte des spires jointives de fils de cuivre recouverts d'un matériau thermoplastique, lesdites spires en hélice étant entourées d'un premier tube en aluminium en contact avec l'hélice, puis d'un second tube d'acier maintenu centré sur ledit premier tube par des supports en matériaux plastiques. Applications : guides d'ondes.
